4 Claims. (01. 153-64) This invention relates to a disc rolling device. Discs of the type used on disc plows and cultivators often become damaged from striking rocks and other obstructions. The damage usually consists of distorting the normal plane of the discs so that they will not freely roll and turn the soil. The principal object of this invention is to provide a device which will quickly roll a deformed disc back to its perfect normal condition.

Disc rolling devices have been used for this purpose, but these devices require that either the discs or the disc shafts be completely removed from the implement and carried to and from the disc rolling device. Another object of this invention is to provide a relatively light, portable, adjustable disc rolling device which will roll and re-form the discs of any type while the latter are in place upon the implement, so as to save the valuable time usually lost in removing and replacing the discs and transporting them to and from a rolling device.

Certain types of discs are formed with a substantially semi-spherical contour, and the usual disc rolling device operates only on the peripheral edge and is unable to follow the arcuate, spherical contour of the disc.- A further object at this invention is to provide a portable disc rolling device which will automatically follow the original arcuate contour or dish of the disc to bring deformed discs back to their original state.

Gther objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efficiency. These will becomernoreapparentfrom the following description.

In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.

In the drawing:

Fig. l is a plan view of the improved disc rolling device, illustrating it in relation to a disc shaft and discs of aconventional farm implement;

Fig. 2 is a rear View of the device;

Fig. 3 is a horizontal cross-section, taken on the line 3-3, Fig. 2;

Fig. 4 is a similar cross-section, taken on the line 44, Fig. 2;

Fig. 5 is a similar cross-section, taken on the line 5-5, Fig 2; and

Fig. 6 is a vertical section, taken on the line 6-45, Fig. 2.

The improved disc rolling device is supported on a track frame consisting of two parallel, V- shaped track members I0 fixedly connected at their extremities by means of cross frame members II welded or otherwise secured to the track members Ill.

The device is mounted on a supporting base plate I2. One side of the base plate I2 is slidably supported from one of the track members I 0 on a V-shaped runner I3 welded to the bottom of the plate I 2. The other side of the base plate I2 is welded or fixedly mounted on a sliding sleeve M which is arranged to travel along a slide rod I5 welded at its extremities to the cross frame members II and positioned in the second track member I0.

The disc rolling portion of the device is supported on a hollow pedestal It, the bottom ofwhich is closed by means of a btotom plate H which projects to one side of the pedestal it to form a clamping shelf I8. The shelf I8 extends beneath a hold-down strap I9 welded at its extremities to the base plate I2 and overlying the shelf I8. A set screw 20 is threaded through the strap I9 and engages the shelf I8 to lock the latter in any desired position.

The pedestal I6 is eccentrically pivoted on a pivot bolt 2I extending through an angle clip 22 welded or otherwise secured on the pedestal I6. It can be seen that by loosening the set screw 20, the pedestal I6 may be swung in an are about the axis of the bolt 2!.

The top of the pedestal lfi is partially closed by two sector shaped, spaced apart top plates 23, the adjacent edges of which are reinforced by means of two parallel guide angles 2 A box-like bearing housing 25 rests upon the top plates 23.".A square, tubular post 2% extends downwardly from thebearing housing 25 between the angle guides 24 and terminates in a threaded nut 21 which is welded or otherwise secured on a square plug 28 fitted into the square post 26.

The nut 21 is threaded onto a horizontal jack shaft 29, which terminates exteriorally of the pedestal It in a hand wheel 38. Rotation of the hand wheel 30 acts to move the nut 21 back and forth in the pedestal I 6, and-the nut 2! acts through the plug 28 and the post 26 to move the bearing housing 25 on the pedestal is parallel to the angle guides 24.

The bearing housing 25 contains a fixed bearing sleeve 3! and a movable bearing'sleeve 32. Each of the bearing sleeves is provided at its extremities with conventional anti-friction shaft bearings, indicated at 33.

The movable bearing sleeve 32 is hingedly mounted on a hinge pin 34 extending through a side bracket plate 35 on the sleeve 32 and a corner bracket plate 36 in the bearing housing 25. The hinge pin 34 is positioned adjacent the rear extremity of the sleeve 32-, and the forward extremity of the latter extends through a horizontally elongated guide opening 31 in the front wall of the housing 25.

A push block 38 is slidably mounted irla guide box 39 adjacent the forward extremity of. the sleeve 32. The push block 38 can be forced against the sleeve 32 by means of an adjusting screw 40 threaded through a head H in the guide" box 39.

A first roller shaft 42 is mounted in the bearings 33 of the fixed bearing. sleeve 31 and projects forwardly therefrom to stationarily support an idler,. disc rolling roller 43 Asecond roller shaft 44- ismounted in the bearings 33 of the movable sleeve 32 and projects forwardly therefrom. to adjustably support a second power-driven, disc rolling roller 45'. i The projectionpfi the shafts 42 and 4'4 are such that the two rollers 43 and 35 contact each-other directly over the pivotbolt 2' l.

The shaft 41- also extends rearwardly from the sleeve 32, and upon this rearwardly extending. portion thereofa: driven sprocket 46' is mounted. The sprocket 4 6 is driven through the medium of a sprocket chain 41 from a drive sprocket 48' mounted on a sprocket shaft 49. The sprocket shaft 49' is rotatably mounted in suitable bearlugs 50 secured on the sidewall of the sleeve 31.

The sprockets 46 and 48 and the chains 41' are preferably enclosed in a safety housing 5!. supported from the housing 25 on suitable brackets 52.

The shaft 49 terminates in any suitable coupling, such as a universal joint 53,. to which a power shaft,- indicated. at 54, may be connected from any suitable source of: power, such. as the power takeoff of a conventional. farm tractor. A suitable carrying handle- 55 is mounted on and projects upwardly from. the bearinghousing' 25- by means of which the device may be carried to the job.

In use, the device, with its supporting track,- is carried to the implement having damaged discs; The track is laid on the ground adjacent the disc shaft of the implement in any convenient position, preferably parallel to the discshaft, and the base plate i2 is moved along the track members In to position the rollers 43' and is opposite the edge of the damaged disc.

The power shaft 5&- isconnected to a source. of power, to rotate the: roller 45 against the disc and. the discagainst the idler roller" 43 The hand wheel 33 is now rotated to force thebearing housing 25 toward the disc so that the rollers 43 and 45 will be forced onto the edge of the disc and toward. the axis thereof while rotating, to iron out any dents, bends, or other irregularities in the discs.

ft will be noted that the base plate 12- is free to move on the track. members [0 and the pedestal i6 is free to' rotate about its pivot bolt Zl to follow the arcuate contour of the disc as the rolling progresses.

Should there be more than one damaged disc, the base plate l2 can be moved along its track to an operating position adjacent the second disc. The rolling pressure applied to the disc is adjusted by adjusting the screw 40 to vary the spacing of the rollers.

For straightening flat discs and the like, the pedestal it" can lee-locked against sideward movement by means of the set screw 20 so that it will force the disc to a true plane condition.

While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.

Having. thus described the invention, what is claimed and desired secured by Letters Patent is:
